GCC compiler collection on Discoverer receives yet another update

Comments 0 Comment

It seems that July has been a busy month for many GCC code developers. The project released a minor new version of GCC, 13.2, which addresses problems discovered in the previously released 13.1 version. More information on the included fixes and changes can be found here: https://gcc.gnu.org/gcc-13/changes.html The code of 13.2 was compiled and installed in the public software repository to provide our users with the most up-to-date version of GCC 13. The build recipe the compilation process is based…

In an effort to support more effective code compilation and code optimisation, we have updated the GCC compiler collection installation available in the public software repository. This update brings to the repository GCC versions 13.1.0, 12.3.0, and 11.4.0. Each new version includes GMP, MPC, MPFR, and iSL libraries. Zstandard 1.5.5 is linked as an external compressor. For optimal workload, we optimised those libraries by adding support for AVX2 SIMD extensions. Currently, AVX2 is the highest SIMD extension supported by the…

The new 15.0.0 version of LLVM compiler infrastructure is out. The source code as well as a set of precompiled binaries are available for download at Github: https://github.com/llvm/llvm-project/releases/tag/llvmorg-15.0.0 Discoverer HPC users now have access to the LLVM 15.0.0 installation available in the software repository. By loading the environment module llvm/15/15.0.0-gcc: module load llvm/15/15.0.0-gcc the users obtain access to the LLVM compiler infrastructure. The suffix “gcc” in the module name specifies the compiler set employed for compiling the source code of…

Which FFTW3 build to use on Discoverer

Which FFTW3 build to use on Discoverer

FFTW3 is an important library package that provides large number of HPC applications with a collection of external subroutines for computing the discrete Fourier transform (DFT) in one or more dimensions. In HPC environment it is a common case to have several different builds of FFTW3 available to support the variety of installed MPI libraries, threads libraries, and common models for application code building, linking, and executing. But in spite how many such builds are presented locally, the most compatible…

LLVM project released version 14.0.6 of their source code. Immediately after that the LLVM compiler infrastructure was compiled and installed in the Discoverer HPC software repository (made available to all HPC users). It is worth mentioning here the way the source code was compiled, since the details of that process reflect the good practice in compiling for AMD Zen2 CPU. The compile recipe is publicly available at: https://gitlab.discoverer.bg/vkolev/recipes/-/tree/main/llvm/ In the recipe, it is better to employ GCC 11 compilers than…
